So after two months of research and testing, I came out with this conclusion: The laptop's hardware is running properly for sure, this can be told from: 1. Games like StarCraft 2, Overwatch, GMod, Sniper Elite 4 run flawlessly, they use different engines like Havok, Source etc. but none of them is Unity; 2. Adobe Premiere Pro renders videos perfectly; Then I noticed all the games with performance issues are build with Unity Engine, for example, Endless Space 2, The Long Dark, Poly Bridge, Layers of Fear, ShellShock Live; The detailed problems while running these games are: 1. They all run with a frame rate below 60FPS, some are even lower; 2. No matter what graphics settings and resolutions I use, they still perform poorly; The following methods are tried but none of them solved the issue: 1. Updating both the Nvidia and Intel graphics driver; 2. Updating BIOS and chipset driver; 3. Disabling functions like power saving; 4. Turning off VSync (the display on this laptop is 4K@60Hz, even if VSync is on, FPS still should not be capped at 30 or lower); 5. Running the games in windowed mode; I used "games with Unity low FPS" as the keyword to search on Google, and found this video: By adding -force-opengl, it fixed my issue with Endless Space 2 but other games refuse to lunch or having trouble display items correctly, Ploy Bridge displays a pink screen by using this command line, however, the FPS showed are around 160, which at least means the game is not struggling with FPS anymore. Now I guess if the games run correctly with OpenGL, maybe it's Unity does not like DirectX very much, but I need more testing to confirm this theory. I will keep looking on the internet, your suggestions will be much appreciated.

So I have sent a email to Gigabyte asking for help, I will keep this post updated in case if anyone has similar issues.

Sorry for the late reply. Yes, I tried to set everything to max performance as much as I can but it just doesn't want to perform well.

I used gaming laptops before and therefore I have a habit of using the laptop while plugged in as much as possible. I have updated the BIOS firmware to V6, which is the latest one I can get from Gigabyte, the CPU is -0.16 undervolted and has no issue running at that voltage.

Yes I have done that, but the performance is still the same after I changed this.

So the story is quite long. I got my Aero 15X a few days ago from my local retailer, the box came perfectly without any sign of opening, however, it came with Windows 10 Home installed, I found this stupid so upgraded it to Windows 10 Pro for Workstations with a legit key I bought and an image file directly from Microsoft. The laptop's hardware is not changed, but even with GTX1070 Max-Q and i7-8750H I am only getting below 30 FPS in all the games, the performance in graphics intense software is poor as well, the only game I can run smoothly is Minecraft for Windows 10 (LOL and WTF?). I tried to re-install the system but it did not help, I also did a stress test with Intel XTU and surprisingly found that the processor cannot go over 2.68GHz which is way lower than it is capable of, it was running at 70°C and 20W which means it was not thermal throttling or power limit throttling. In addition, all the drivers are up-to-date and no anti-virus software is installed, I have checked things like power plan and set the prefered GPU to GTX1070 but none of these helped. The computer can manage files and browse internet normally, I cannot feel any lag while doing these tasks. Could the reason be the single channel memory? I am planning to upgrade to dual channel but I don't want to touch the hardware before the problem is confirmed. Thanks a lot for the attention, please contact me if you know the possible solution for this case. By the way, I have attached the dxdiag file down below, hope it can help. DxDiag.txt Edit: Just found that the laptop also lags really a lot while Task Manager is running (WTF?).

I definitely want the new Blade, so I don't need to carry my heavy Alienware around any more, it's lighter, thinner, and more powerful (GTX 1060 is definitely better than GTX 980M).
